Let's be real: When it comes to enjoying the "Twilight" movies, suspension of disbelief is a key factor. There's the whole "vampires are sparkly" thing; the whole "accelerated hybrid pregnancy" thing; the whole "pretend like you didn't notice Kristen Stewart's horrible wig" thing...

And then there's the fact that, in "Breaking Dawn," the ridiculously fresh-faced Elizabeth Reaser is supposed to be somebody's grandmother. Crazy! So when we caught up with the actress who plays Esme Cullen at the Sundance Film Festival, we had to ask what she thinks about Mackenzie Foy, the 10-year-old actress who plays Bella-Edward offspring Renesmee Cullen.
